Abstract: An electronic device includes a display screen, a display control circuit, an active optical component, and an optical control circuit. The active optical component is located below the display screen. The display control circuit is configured to control refreshing of the display screen, and output a synchronization signal to the optical control circuit. The optical control circuit is configured to receive the synchronization signal, and control the active optical component to start light emission after a predetermined first delay that is after a moment corresponding to the synchronization signal to enable the display control circuit to refresh to one row of at least one row on the display screen corresponding to the active optical component after a predetermined second delay that is after the active optical component completes light emission.

Abstract: An imaging method and apparatus, a radar system, an electronic device, and a storage medium are provided. A first target image is obtained by obtaining at least two groups of original radar data from different radars, and performing image registration and time-domain coherent superposition. Each group of original radar data corresponds to one radar. The original radar data from the different radars includes different radar information. After image registration and time-domain coherent superposition are performed on the original radar data, the obtained first target image has higher physical resolution. Therefore, resolution of a generated radar image is improved, image information in the radar image is enriched, and positioning accuracy and driving safety of a vehicle are improved.

Abstract: Embodiments of this application disclose an electronic device, including a display screen, a display control circuit, an active optical component, and an optical control circuit. The active optical component is located below the display screen. The display control circuit is configured to control refreshing of the display screen, and output a synchronization signal to the optical control circuit. The optical control circuit is configured to receive the synchronization signal, and control the active optical component to start light emission after a predetermined first delay after a moment corresponding to the synchronization signal, so that after a predetermined second delay after the active optical component completes light emission, the display control circuit refreshes to one row of at least one row on the display screen corresponding to the active optical component.
